When you initially input income, specifically capital gains, you have no idea what will be left to distribute. If you under distribute, the trust pays a higher tax on any residual income. If you over distribute, the beneficiary overpays unnecessary taxes. The program should either have a feedback loop or a couple of alerts. One alert should be at where you originally input capital gains income, and another where distributions are entered.
